SwiftAA 2.0

SwiftAA, the most comprehensive collection of accurate astronomical algorithms just reached v2.0! This is the first version of complete Solar System APIs with units safety and a whopping 90%+ of unit tests coverage.

I am very proud of the result. Lots of things remain in the pipe for an even more amazing v3, but here you have: a complete set of easy-to-read and documented APIs to compute everything you need about the solar system.
